I don't think it's a popular type. 'Fairy Tail' is known for its epic adventures, strong friendships, and magic - based plotlines. A fanfiction with a plot like Natsu spanking Lucy seems out of place and may not gain much traction. It goes against the more mainstream ideas of the relationship between the two characters that fans are used to.
In such a fanfiction, it could be about how this action of Natsu spanking Lucy might be a form of discipline within the context of their guild. It might show a different side of their relationship, perhaps a more mentor - mentee kind of dynamic that hasn't been fully explored in the original series. But it's important to note that this is a very specific and somewhat unorthodox take on the characters.
A lot of fanfictions focus on the idea of Natsu and Lucy being forced to work together in a tournament. They have to overcome their differences and use their combined skills to win. This often leads to a better understanding of each other. There are also plotlines where Lucy discovers a new and powerful form of her celestial magic and Natsu helps her master it. Sometimes, a prophecy about their combined destiny is revealed, which sets them on a journey to fulfill it.
Sure, there may exist such fanfictions. In the official 'Fairy Tail' story, Natsu and Lucy are very close. But fanfiction is a world of creativity and deviation from the original. A writer might decide to make Natsu hate Lucy due to some made - up reasons like a misunderstanding or a conflict of interests. This could lead to a whole new set of adventures or conflicts within the 'Fairy Tail' universe as rewritten by the fanfiction author.
Yes, there might be such fanfictions in the vast world of 'Fairy Tail' fan creations. However, these types of fanfictions can vary greatly in terms of their content and quality. Some may focus on the comical aspect of such a situation, like Natsu accidentally stumbling into Lucy's bathing area and the chaos that ensues. Others might use it as a way to develop their relationship in a more platonic or budding romantic way within the fan - created narrative.
There's a fanfic titled 'Married Life in Magnolia' which focuses on their day - to - day married life. It includes Natsu being his usual goofy self and Lucy trying to keep him in line while they both deal with the challenges of being a married couple in the Fairy Tail guild.
There are those that focus on their friendship turning into a deeper romantic relationship during a time of peace in the Fairy Tail guild. For example, they might participate in a guild - wide event that makes them realize their true feelings for each other. These stories usually have a lot of sweet and heart - warming moments between them.
Some popular themes include their rivalry as well. They might compete to see who can defeat a certain enemy first or who can master a new spell faster. This adds an interesting dynamic to their relationship. And there are also fanfictions that focus on them being part of a team within the Fairy Tail guild, working together with other members to achieve a common goal, like saving the guild from a major threat.
A common storyline is when Lucy's celestial spirits play a role in bringing Lucy and Natsu closer. For example, one of her spirits could give Natsu a task that involves protecting Lucy at all costs. This leads to them spending more time together and sharing deeper conversations. Another idea is that a powerful enemy targets Lucy specifically because of her connection to the celestial world, and Natsu is determined to keep her safe no matter what. This shows his loyalty and could develop into a more romantic relationship as the story progresses.
One popular scenario could be after a major battle where they both realize their deep feelings for each other. Natsu, being the impulsive and passionate character he is, might just grab Lucy and plant a kiss on her. Another could be in a moment of great celebration in the guild. With everyone around them having a great time, Natsu and Lucy get caught up in the moment and share a kiss. And sometimes, it might be in a more private, tender moment. Maybe Lucy is feeling down, and Natsu tries to comfort her in a more intimate way, leading to a kiss.
In a fanfiction of Natsu and Lucy at the spa, the spa could be a place where they face some challenges too. Maybe there's a villain who tries to disrupt the peaceful spa environment. Natsu and Lucy would then have to use their skills, not just in combat but also in keeping the other guests calm. Natsu's fiery nature and Lucy's intelligence would work together to solve the problem, all while still in their spa robes. And in the end, they might realize they make a great team even in such an unexpected place.
